SIGMUND KOHN, OF VIENNA, AUSTRIA-HUNGARY, ASSIGNOB TO THE FIRM OF JACOBSt JOSEF KOHN, OF SAME PLACE.

CHAIR-LEG FASTENER.

SPECIFICATION forming part of Letters Patent No. 296.336, dated April 8,1884.

Application led October E29, 1883. (No model.)

Be it known that I, SIGMUND Kenn, eresident of the city of Vienna,Austria-Hungary, have invented a Chair-Leg Fastener, of which thefollowing is afull, clear, and exact description, reference being madeto the accompanying drawings, in whichm Figure l is a perspective viewof a chair bottom and leg connected by my improved fastener. Fig. 2 is avertical central section of my improved fastener. Fig. 3 is aperspective view ofthe same. Fig. 4 is a vertical section at rightangles to Fig. 2.

' This invention relates to a new means for connecting chair-legs to thechairbottoms,

and for likewise connecting other articles of furniture. i

The invention involves the employment of a screw and nut, the screwbeing secured in 2o the leg and the nut in the chair bottom or plate.Such connections havebeen employed before my present invention; but theobjection to them has been that the screw, in being secured into the legin which the grain of the 25 wood was running longitudinally, was liableto split the wood, and from this cause the metallic connections, whichotherwise would be very desirable, have failed to become established inthe market.

My invention consistsjn employing, kin connection with the screw, asheet-metal cap, which enters with its vertical sides into the wood ofthe chair-leg, and prevents it from being split by the screw that isafterward introduced.

In the drawings, the letter A represents a chair-leg, and the letter Bthe seat or bottom to which the said Vleg is to be attached; or theparts A B may be assumed to represent other 4o portions of the articlesof furniture requiring analogous means oi' connection.

C is a screw, and D a nut, by which the parts A B are to be joined. Thescrew Chas its lower portion threaded, so that it will be adapted to besecured in the wood of the leg A. lts upper portion, however, isthreaded,

so aste iit it into the nut D. Between these different threads the screwC has a shoulder, a, for the reception of which the upper end 5o of theleg A is hollowed out; or instead of this the lower face of the part Bmay be holof the article of furniture which contains it.

lowed out to receive this shoulder a wholly or in part.

E isa sheet-metal cap-that is to say, an inverted sheet-metal cup-whichis inserted in the upper part ofthe chair-leg A, so that its verticalwall will enter into the wood, as is clearly indicated in Fig. 2, andwill surround in that position the upper portion of the screwr O, thatenters the wood of the chair-leg A. 6o The shoulder a on the screw is bypreference angular or dat, so that it may be taken hold of by a wrench.In practice I prefer to ream out of the upper end of the chair-leg A thecavity which is to receive the shoulder a, and to make that cavity largeenough to allow the sheet-metal cap E to be inserted and forced home, sothat it will rest on the bottom ot' said cavity, as indicated. l mayeven cut an annular recess into the chair-leg for the more convenientinsertion of the vertical walls of the cup E. Vhen this cup has beenwholly or partly fitted to its place, the screw C is se- 'cured in thecha-inleg until its shoulder bears 8o The nut D is fitted into a cavityprepared for its reception in the seat B, so that the chairleg havingthe protruding portion of the screw C may be conveniently attached.

Fig. 4 shows the transverse cavity or recess made for the insertion ofthe nut D, which, when the nut is in place, is closed again by a plug,b.

I claiml. The combination of the screwC, having shoulder a, with thehollow cap E and nut D, substantially as herein shown and described.

2. The combination of the wooden chairleg A, which is recessed at itsupper end, with the hollow cap E, screw C, having shoulder a, 95 andwith the nut D and seat B, substantially as herein shown and described.
